Cleaning

Gently wipe the earbuds and charging case with a soft, dry, lint-free cloth. Do not use abrasive cleaners or solvents. For the eartips, remove them and clean with a damp cloth, ensuring they are completely dry before reattaching.

Troubleshooting

If you encounter issues with your Boult Z40 Ultra earbuds, refer to the following common problems and solutions:

• Earbuds not pairing: Ensure both earbuds are in the charging case, then open the lid to activate pairing mode. Check that Bluetooth is enabled on your device and that the earbuds are selected. Try forgetting the device on your phone and re-pairing.
• Only one earbud working: Place both earbuds back into the charging case, close the lid for a few seconds, then open it again. This often re-syncs them. Ensure both earbuds have sufficient charge.
• No sound: Check the volume level on both your device and the earbuds. Ensure the earbuds are properly connected to your device. Try playing audio from a different application or device.
• Poor sound quality: Ensure the earbuds are clean and free of debris. Try different sized eartips for a better seal in your ear canal. Move closer to your connected device to avoid interference.
• Charging issues: Ensure the charging cable is securely connected to both the case and the power source. Check if the charging port is clean. Try a different charging cable or power adapter.
• ANC not effective: Ensure the earbuds are properly seated in your ears to create a good seal. The effectiveness of ANC can vary based on the type of noise.

If the issue persists after trying these steps, please contact Boult customer support for further assistance.
